This branch of the science has reached the highest development in its application to the history of the extinct mammalia of the Tertiary through the original work o Cope and Henri Filhol, which has been brought to a much higher degree of exactness recently through the studies of H.
It is apparent, even from the brief summary just given, that the importance of Hume in the history of philosophy consists in the vigour and logical exactness with which he develops a particular metaphysical view.
At the same time, his characteristic exactness makes his collection a most admirable substitute for the texts of the many valuable treatises of earlier mathematicians of which time has deprived us.
We have next to examine the manner in which he used it, and here we are met at the outset by the difficulty of determining with exactness what authorities he is following at any one time; for of the importance of full and accurate references he has no idea, and often for chapters together he gives us no clue at all.
But the book of Acts, our only continuous authority for the period, contains two synchronisms with secular history which can be dated with some pretence to exactness and constitute fixed points by help of which a more or less complete chronology can be constructed for at least the latter half of the apostolic age.
The points just noted apply also to the average fluctuation and the standard deviation, but it is probable in these cases that daily or even weekly quotations would be sufficient to yield the information sought for with sufficient exactness for purposes of comparison.
His criticisms are worth more than his constructions; indeed for exactness and penetration of thought he is quite on a level with Hume and Kant.
The situation of Athens relatively to the surrounding objects is singularly harmonious; for, while it forms a central point, so as to be the eye of the plain, and while the altar-rock of the Acropolis and the hills by which it is surrounded are conspicuous from every point of view, there is no such exactness in its position as to give formality, since it is nearer to the sea than to Parnes, and nearer to Hymettus than to Aegaleos.
To neither question can an answer be given in terms so precise as to exclude some latitude, but to both with sufficient exactness to rule out at once three of the six years.
This is said to have hapC, pened in 356 B.C. on the October night on which Alexander the Great came into the world, and, as Hegesias said, the goddess herself was absent, assisting at the birth; but the exactness of this portentous synchronism makes the date suspect.
